Jonesville and smithville each have a population of size 2600 at time t = ​0, where t is measured in years. Suppose jonesville​'
ehidna [41]

Answer: B. Jonesville is growing linearly and Smithville is growing exponentially.

Step-by-step explanation:

Linear growth :

  • Population grow by a constant amount after each time period.
  • The rate of change of dependent variable with respect to independent variable is a constant.
  • It is represented by line on graph.
  • Equation for linear growth : y=mx+c , c = initial value and m is the rate of change of y with respect to x.

Exponential growth :

  • Population grow by a constant ratio .
  • It is represented by a curve on graph.
  • Equation for exponential growth : y=a(1+r)^x , a = initial value and r is  rate of growth ( in decimal ) and x is time period.

Given : Jonesville​'s population grows by 170 people per year.

i.e .Population grow by a constant amount per year.

⇒ Jonesville is growing linearly.

The population of smithville grows by 7​% per year.

i.e. Population grow by a constant ratio.

⇒Smithville is growing exponentially.

Hence, the true statement is "B. Jonesville is growing linearly and Smithville is growing exponentially."

QUESTION.<br> What is an improper fraction? An improper fraction:<br> Does anyone know this?
Kruka [31]

Answer:

An improper fraction is when the numerator of the fraction is larger than the denominator

For example, 13/4 is improper because 13 > 4

An improper fraction can be changed into a mixed number by dividing the numerator by the denominator

For example, 13 divided by 4 is 3 with remainder 1, or 3 1/4

A researcher is interested in the lengths of brook trout, which are known to be approximately Normally distributed with mean 80
aliya0001 [1]

Answer:

P(X

And we can find this probability with the normal standard distirbution or excel and we got:

P(z

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".  

Solution to the problem

Let X the random variable that represent the lenghts of a population, and for this case we know the distribution for X is given by:

X \sim N(80,5)  

Where \mu=80 and \sigma=5

We are interested on this probability

P(X

And the best way to solve this problem is using the normal standard distribution and the z score given by:

z=\frac{x-\mu}{\sigma}

If we apply this formula to our probability we got this:

P(X

And we can find this probability with the normal standard distirbution or excel and we got:

P(z
